This invention relates'to pitmen designed especially for use inconnection with mowers or other desired machinery and has for an objectto provide an extremely simple pitman having a leather bushing for thewrist 'pin, whereby wear-may be easily taken up, and also sif'chleatherbushing protecting the wrist pin from the usual annoying wear.

' man having means for lubricating the bush- A stillfurther object is toprovide a piting, and also having means for taking up avear upon thebushing.

A still fprther object is to provide an extremely simple, strong anddurable pitman that will be formed of a few parts that will not easilyget out of order.

With the above objects in view the invention consists of certain noveldetails of construction and combination of parts hereinafter fullydescribed and claimed, it being understood that various modificationsmay be made in the minor details of construction within the scope of theappended claim.

In the accompanying drawing illustrating this invention :Figure 1 is aside elevation of the pitman. Fig. 2 is a longitudinal sectional viewthrough the pitman. Fig. 3 is a cross sectional view on the line 33 ofFig. 1. Fig. 4 is a detail perspective view of the bushing.

Referring now to the drawing in which like characters ofreferencedesignate similar parts, 10 designates a pitmau having aheadbearing including an integral member 11 and a member 12 hinged tothe member 11 by a pin 13, there being clamp lips 14 and 15 on theintegral member and the hinged member respectively through whichSpecification of Letters Patent.

clamp drawing the lips together to take up wea upon the bushing. Thebushing 17 is'formed of leather and is in the nature of a split ringadapted to snugly fit in the inclosure of the bearing and havingparallel lips 18 adapted to be confined between the clamp lips 14 and 15of the bearing. An oil duct 19 is formed longitudinally in the pitnianand communicates with the bushing, there being a lubricant cup'20threaded through the side of the pitman and communicating with the ductto supply the lubricant thereto. A lag screw 21 is threaded through theside of the pitman and projects across the duct in the rear of thelubricant cup and metal bushings, and furthermore, Wear' upon thisbushing may be takenup when necessary by simply tightening the clampbolt 16.

From the above description it will be seen that I have provided anextremely-simple, light, and strong pitman that will be formed of a fewpartsthat will not easily get out of order.

What is claimed, is

A pitman including an integral clamping element, a movable clampingelement hinged at one end to the adjacent end of said integral element,said integral and movable elements having their opposed faces concavedto provide a bearing seat and their other ends terminating in parallellips provided with registering openings, a flexible strap beg-ringarranged within the concavities of sgfd elements with its ends directedbetween said lips and apertured to register with the openings in thelatter, and a clamping bolt engaged through the lips and strap to0perate said clamping elements an" hold said strap against lateraldisplacem..-
